BromohydrinsCHEMONTID:0002607Alcohols substituted by a bromine atom at a saturated carbon atom otherwise bearing only hydrogen or hydrocarbyl groups.
BromophenolsCHEMONTID:0002764Halophenols carrying a bromine on the benzene ring.
Bufanolide glycosides and derivativesCHEMONTID:0001558Bufanolides that are glycosidically linked to a glucose moiety.
Bufanolides and derivativesCHEMONTID:0001557Steroid lactones containing a pyran-2-one moiety linked to the C17 atom of a cyclopenta[a]phenanthrene derivative.
ButenolidesCHEMONTID:0002223Dihydrofurans with a carbonyl group at the C2 carbon atom.
ButyrophenonesCHEMONTID:0000350Compounds containing 1-phenylbutan-1-one moiety.
Buxus alkaloidsCHEMONTID:0002726Alkaloids with a triterpenoid-steroid pregnane type structure with C-4 methyl groups, a 9beta,10beta-cycloartenol system, and a degraded C-20 side chain. Structurally, they are derivatives of either a 9beta,10beta-cyclo-4,4,14alpha-trimethyl-5alpha-pregnane or a 9(10->19)abeo 4,4,14alpha-trimethyl-5alpha-pregnane system.
